ysetting diethe length ofthe feed step being controlled by the movement of a feed arm which. cross-reciprocates a punch head carrying the combined punch and upper setting die. ilhe feed takes place while the punch is in the work. The length of feed is regulated by varying the etiective strolie of the feed arm through a pin plate having a plurality of holes, any one of which may receive a controlling pin, the position of which in the plate determines, through suitable connecting mechanism, the amplitude ofmovement of the feed arm. rl`he requisite length of feed for any particular size or style of shoe is determined by the sliill of the operator in selectinO' the proper hole in which to place the controlling pin.

rEhe object of the present invention is to eliminate the judgment of the operator in determining the spacing required for the proper insertion of eyelets, or other fasteners, in different sizes and styles of shoes, or in other Work where a variation in spacing is essential.

ln accordance with this object, a feature of the invention comprises a fastener spacing attachment, for machines of the character indicated, which can be set by the operator according to instructions previously worked out, making it necessary or the 0perator merely to follow certain definite and very simple directions when changing from one required spacing to another. To this end, a simple form of pin plate is provided with which there is employed one of a number of interchangeable templets so designed as to render ineffective all of the pin holes except those required in spacing fasteners for the different sizes of the style of shoe for which the templet was made.. Each templet bears a symbol corresponding to the symbol on the tag of a rack or case of shoes. Consequently, the operator need only select from the templets that one of the same symbol as that on the tag of any case of slices to be -operated upon, secure this templet to the pin plate, and then proceed with her work, using for the various sizes the pin holes which the templet leaves uncovered. The designs of the templets provide for the proper location of the first and last fastener relative to the ends of the worlr and for the line gradations in spacing required by variation in size, without requiring the operator to punch severalv shoe uppers, with varyino' adjustments, before the proper adjustment is determined. rihe use of the present invention insures uniformity of work, perfects the shoe making, and saves the time of the perator.

In the embodiment of the invention illustrated in the drawings, the eyelets are set between a combined upper die and punch l0 on a rain l2 and a lower die le on a ram 16. These rams are given vertical reciprocating motion from mechanism actuated. by a cam shaft 18, the lower ram through a crank pin 2O and the upper ram through a cra-nk pin 22, which mechanism is like that illust-rated and described in said patent to haulenschlager.

'lhe novel mechanism lior controlling the spari '1' olf the eyelets, through the train ot niechanisni just .referred to, will nonT be described. Attached to the machine traine at the roar ot the lever arin is a horizontally projecting1 bracket 8G comprising' a vertical plate to the rear side ol which there is attached an inverted "l'sliaped plate, by means of the bolts and pins shown in Figs. l and 3, extending through its vertical arni 38. it the upper end ol' the vertical erin 38 is a hearini` tor a horizontal pin Ll() projecting,r troni one end ot a crank erin d2, at the lront loro the erin. rllhe other end ci? the crank minet-ted by ineens et a vertical link v `h the outer end o, the leicr rl`his is piroted to the cranl; arin at its niiper end and is connected to the lever lll bj' being' pivoted to a collar Llll secured to the end ot the lever. The piu l0, :it the rear tace ol the vertical arni 3S, has a` siacing ineinber d8 mounted thereon, and a depending rod is secured thereto comprising a thin tlexihle strip, the lower end ot Which 'terminates in a handle 52. This handle is hollow and receives within it a lever pivoted at its lower end upon a transverse iin 5o: said lever terminating at its upj er end in a pointer 5S which projects over the liront tace oit' the horizfzontal arin 39 ot' the inrered l'- shaj'ied plate. A coiled spring4 o0, as shown in Fig. 3, operates to continuallji' maintain the pointer 5S in Contact with the liront lace oli the plate erin 3.. The rear side ol the handle 52 is provided with an inwardlv projeotingl pin G2, opposite the pointer, adapted to enter any one oli a plurality ot' pin holes (Selin the horizontal arin 39 torined ou :i are struck from the axis ot the pin Ll() as a centre.

The portions in the teniplet usually render arailable holes 1:1 The pin plate which are interlil tif)

spersed among the entire set of holes in the plate, so that the positions in which the pin .G2 may be adjusted are' separated by one or more intervening positions of adjustment which are obstructed by thev templet. ln order to secure the templet in its operative position it is provided in one end With a horizontal slot 7a so that this end can be slipped under a headed pin 76, Fig. 4, which projects from the back of the pin plate 39 at one end thereof. A hole 78 is formed in the opposite .end of the templet to register with a' hole 80 in the other end of the pin plate. The forward side of the pin plate adjacent the hole 80 is provided with a proj ecting housing 82 Within which slides a push pin 8i projecting through the rear face oft-he pin plate and having at its rear end an offset head 86 carrying a forwardly projecting pin 88. lWhen the head 86 is rotated into engagement with a stop pin 89 on thev pin plate, the pin 88 is then in alinement with the holes 78 and 80. A coil spring 90 surrourdimT the pin 84 Within the housing 82, as shown in Fig. 5, normally maintains the pin 88 in a position of engagement with the hole 80. in order to remove the templet G8 from the pin plate, the pin 84ris depressed, thus removing the pin 88 from the holes 78 and 8O and is then rotated to turn it head 86 down against a. stop pin 92 where it is clear of the end of the templet. ri-"he templet may then be removed, to permit substitution of another, by Witiidraiving its opposite end from beneath the pin 7G.

lt will be understood that there are a sufficientfnumber of. interchangeable templets, each marked With a symbol, as shown in Fig. 6, which together correspond to all the symbols used on the casevtags to indicate the various styles of shoes that are to be operated upon. Consequently when a new case of shoes is brought to the operator, she inspects the tag, selects the templethaving the same symbol as that on the tag, places the templet in position onV the pin plate, and then proceeds with her Work. She lrnoivs that all the pin holes are covered except those for properly spacing fasteners for 'the sizes of the style in hand, that the open hole farthest to the left is for the smallest size, and that the open hole at the other end is for the largest size. The shoe uppers are taken in regula-r order as to size, and for perfect spacing it is merely necessary that the controlling handle be moved over the space of one hole, starting at one end, for each new size. The openings in the templets are so selected, for the style indicated by the symbol thereon, that the spacing adjustment locates the first and last fasteners at the proper distance from the bottom and top of the Work for all sizes of that particular style. It is, therefore, unnecessary when using the present invent-ion for the operator to mal-:e

a o any trial adjustments of the spacing mechanism" since by its use all the determinations formerly left to the judgment and skill of the operator are eliminated. Usually a given order includes only a comparatively small'number of sizes of a certain style so that only a very few positions of the adjusting arm need be provided for on a single templet. In fact this number obvious I can be reduced, so far as may be decine-fl ad able, by increasing the number of teinplets employed and using suitable syn'ibol:
